Model-independent search for the decay B+-> l(+)nu(l)gamma
- Abstract:
-
We present a search for the radiative leptonic decay B+→≤+ v≤ γ, where ≤=e, μ, using a data sample of 465×106 BB̄ pairs collected by the BABAR experiment. In this analysis, we fully reconstruct the hadronic decay of one of the B mesons in Υ(4S)→B+B- decays, then search for evidence of B+→≤+ν≤γ in the rest of the event. We observe no significant evidence of signal decays and report model-independent branching fraction upper limits of B(B+→e+νeγ)<17×10-6, B(B+→μ+νμγ)<24×10-6, and B(B+→e+ν...

Content may be unavailable for the following four reasons
-
Version unsuitable
-
We have not obtained a suitable full-text for a given research output. See this page for more information.
-

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text
